Syftet med denna studie är att undersöka individers riskbeteende vid investeringar samt få en djupare förståelse för arbitrage och den osystematiska risken som är involverad när en individ utnyttjar arbitragemöjligheter. För att undersöka detta har en avgränsning gjorts till oddsmarknaden och riskfritt arbitrageutnyttjande i form av Surebets. Detta har undersökts med hjälp av kvalitativ- och kvantitativ metod i form av en triangulering. Genom en enkätundersökning och intervjuer kunde ett kausalt samband identifiera beteendesvängningar hos individer när det kommer till vinst och förlust. Ett Eta2-test genomfördes och påvisade ett samband mellan individers riskbenägenhet och kunskapen om Surebets. Studien fann flera osystematiska risker för användarna kopplat till Surebets varav den största är spelbolagen och dess användaravtal. Avslutningsvis kan nollhypotesen förkastas med hjälp av Eta2-testet samt ett kausalt samband, vilket bevisar ett högre risktagande bland individer som utnyttjar arbitrage på oddsmarknaden. / The purpose of this study is to investigate individuals' risk behavior during investments and to gain a deeper understanding of arbitrage and the unsystematic risk involved when an individual uses arbitrage opportunities. To investigate this a delimitation has been made to the odds market and the risk-free utilization of arbitrage in the form of Surebets. The method used to investigate this has been a qualitative and quantitative method in the form of a triangulation. Through a survey and interviews, a causal relationship could identify behavioral fluctuations in individuals when it comes to profit and loss cases. An Eta2 test was conducted and demonstrated a connection between individuals' risk behaviour and the knowledge of Surebets. The study found several unsystematic risks for users linked to Surebets, where the largest are the gaming companies and its user agreement. Finally, the null hypothesis can be rejected by means of the Eta2 test and a causal relationship, which proves a higher risk taking among individuals exploiting arbitrage opportunities on the odds market.

The sunk-cost fallacy (SCF) occurs when an individual makes an investment with a low probability of a payoff because an earlier investment has already been made. It is considered an error because a rational decision should not factor in now-irretrievable investments, as they do not affect current outcome likelihoods. Previous research has measured the tendency to commit the SCF by using hypothetical scenarios in which participants must choose to make a future investment or not after making an initial investment. There are many theories as to why people commit the SCF. Loss aversion, which is the preference for uncertain over certain losses, may be related to the SCF. Dual-process theory, which views decision-making in terms of a fast, automatic process called system 1 and a slow, deliberate process called system 2, may also help to explain the SCF. In Experiment 1, participants were asked to complete a sunk-cost questionnaire in which the initial-investment types and amounts varied. They also completed an endowment-effect task as a measure of loss aversion. The SCF was committed most often when the initial investment was large compared to small and most often with money, less with time, and least with effort. There was an interaction effect in which small differences were seen in the SCF between time, effort, and money when the initial investment was small, and differences grew larger as the initial investment increased. Loss aversion displayed a non-significant negative relation with the SCF. In Experiment 2, participants completed a sunk-cost questionnaire in which they were asked to respond as they normally would and then from the perspective of a fictional person described as a logical decision maker. In cases in which they committed the SCF, they were asked to indicate why they continued to invest. They also completed a risky-lottery loss-aversion task. As seen in Experiment 1, the SCF was more likely when initial investments were greater and occurred most when the initial investment was money, less when it was time, and least when it was effort. Loss aversion had a significant but small negative relation with SCF scores. There was no effect of perspective taking. It may be that the SCF is simply due to the over-application of the personal rule “don't waste”, as not wanting to be wasteful was the most-common reason participants gave for why they committed the SCF.

With the growth of fashion consumption through websites and e-tailers, the question of when and why consumers engage in shopping without the intent to purchase has gained new relevance. A novel framework for understanding this phenomenon comes from studies examining the neural basis of aesthetic appreciation. Previous studies in neuroaesthetics have identified brain regions associated with value and reward, including the nucleus accumbens (NAcc) and ventromedial prefrontal cortex (VMPFC), as involved during attractiveness judgments even when no physical product is consumed. Along with research demonstrating that attractive stimuli can serve as economic incentives to motivate behavior, these results suggest that the experience of aesthetic appreciation can have value in and of itself, similar to the hedonic value previously proposed to explain shopping without the intent to purchase. The proposed study examines whether fashion browsing can be considered a type of aesthetic experience. Functional magnetic resonance imaging (fMRI) will be used to measure neural activation as female subjects (N=50) view fashion images. If fashion browsing is a type of aesthetic experience, we would expect it serve as an economic incentive and motivate work. Additionally, the NAcc and VMPFC during browsing should show increasing activation with increasing attractiveness of fashion content. Individual differences in self-reported fashion browsing behavior will correlate with the degree of neural differentiation to fashion content such that individuals who spend more time per week browsing will have higher BOLD signal NAcc and VMPFC activation during the experimental task. Fashion browsing as an aesthetic experience could serve as a crucial mechanism to develop a greater understanding of an important aspect of the consumer shopping experience.

Environmental goals such as urban water conservation and pollution control regulations are typically achieved through price and non-price methods. This dissertation offers an analysis of the non-price approaches, including the rationing of water for particular users, installation of particular technologies, and adoption of particular certifications to achieve environmental goals. To begin, an analysis of California’s 2015 urban water conservation mandate was performed. Results indicate that the average welfare loss of the mandate is $6,107 per acre-foot of restriction in Northern California and $2,757 per acre-foot of restriction in Southern California. In terms of monthly household-level willingness-to-pay (WTP) to avoid the mandate, results illustrate that households have a WTP between $5 and $200 per month. Northern Californian utilities were generally in compliance with their mandated conservation targets, while Southern Californian utilities tended to fall short. The second essay focuses on analyzing how web-based Home Water Use Reports (HWURs) affect household-level water consumption in Folsom City, California. The HWURs under study, offered by the company Dropcountr (DC), share social comparisons, consumption analytics, and conservation information to residential accounts, primarily through digital communications. We found that there is a 7.8% reduction in average daily household water consumption for a typical household under treatment of the DC program. Results suggest that the effect of DC varies by the baseline consumption quintile, the number of months in the program, the day of the week, message type, and enrollment wave. Furthermore, we find that indicate these responses to DC program likely come from the information channel rather than moral suasion. The final essay studies the effectiveness of ISO-14001 on pollution reduction as a non-price pollution control approach. Manufacturers have been increasingly relying on environmental management systems (such as ISO 14001 based ones) to comply with government regulations and reduce waste. In this essay, we investigated the impact of ISO 14001 certification on manufacturers’ toxic release by release level. Results show that ISO 14001 had a negative and statistically significant effect on the top 10% manufacturing sites regarding the on-site toxic release, but it did not reduce off-site toxic release. Therefore, one should not expect ISO 14001 to have a uniform impact on manufacturing sites’ environmental performance. For large firms, encouraging voluntary adoption of ISO 14001 might be an effective government strategy to reduce on-site pollution.

Mortgage loan debt is prevalent among middle-aged and older Americans. With higher average outstanding balances, many people are unlikely to pay off their mortgage debt by retirement. Meanwhile, as people age, health shocks are more likely to occur. Medical expenses may compete with mortgage payments and relate to financial insecurity in later years. In order to alleviate financial strain during times of financial hardship, senior homeowners may find reverse mortgage the solution they are looking for. Targeting American adults age 50 and older, this dissertation investigates mortgage loan debt and financial security using panel data from the Health and Retirement Study. Chapter 1 provides an overview of this dissertation and three studies. Chapter 2 investigates whether retirement preparedness plays a role in mortgage status at retirement, shown here as whether a person has mortgage debt and how much the remaining balance is (Waves 2004-2014). Chapter 3 examines health impact on likelihood of paying off mortgage loans under different health conditions, with estimates on expected time to mortgage payoff (Waves 2004-2014). Chapter 4 focuses on reverse mortgages and their impact on senior borrowers’ financial satisfaction and liquidity constraint (Waves 2010-2016). Chapter 5 summarizes major findings in three studies and highlights the contribution of this dissertation toward middle-aged and older Americans’ financial security. Limitations of three studies are discussed in Chapter 6. Three studies provide evidence on 1) the importance of preparedness on reduced mortgage burden; 2) adverse impact of health shock on likelihood of mortgage payoff; and 3) using reverse mortgages to reduce financial strain and increase financial satisfaction. Implications are addressed in each study.

Our energy system is rapidly transforming, partially due to advances in internet and communications technologies that leverage an unprecedented amount of data. Industry proponents of the so-called “smart grid” suggest these technologies facilitate deeper engagement with end-users of energy (utility customers) that can in turn drive behavior-based changes and accelerate a renewable energy transition. While there has been progress in understanding how these technologies change consumer behavior using, for example, real-time feedback, it’s unclear how specific segments (e.g., renters) respond to these interventions; it’s also unclear why feedback is, or is not, producing changes in energy consumption. The literature suggests that behavioral strategies (e.g. information feedback, competitions, incentives) coupled with technology may present a way for utilities and efficiency programs to create savings—expanding opportunities for those often underserved by traditional approaches, such as renters—yet this coupling is not well understood, neither broadly (for all end users) nor specifically (for renters). This dissertation builds upon that literature and explores a human side of the smart grid, using a field experiment in renter households to test the interacting effects of real-time energy feedback and a novel form of financial incentive, referred to here as a competitive performance-based incentive. The experiment had two phases: phase one tested the feedback against a control group; phase two tested feedback, the incentive, and a combined treatment, against a control group. Results of these interventions were measured with pre- and post-treatment surveys as well as observed electricity consumption data from each household’s smart meter. The results of this experiment are described in three papers. Paper one examines the interventions’ individual and combined effectiveness at motivating renters to reduce or shift timing of electricity consumption. Feedback alone produced a significant savings effect in phase one. In phase two, the effect of the feedback wore off; the incentive alone had no significant effect; and the group that received feedback and the incentive experienced a doubling of savings relative to the effect of feedback alone, as observed in phase one. Paper two uses pre- and post-intervention survey data to examine how individual perceptions of energy change as a result of the interventions. Perception of large energy-using appliances changed the most in households that received feedback, suggesting that better information may lead to more effective behavior changes. Paper three leverages the results of the first two components to evaluate the policy implications and impacts on demand side management for utilities, efficiency programs, and the potential for behavior-based energy efficiency programs. Advocates of the smart grid must recognize the technology alone cannot produce savings without better engagement of end-users. Utility rate designers must carefully consider how time-based rates alone may over-burden those without the enabling technology to understand the impact of their energy choices.

On June 29, 2011, President Barack Obama held a press conference regarding the nation's budget deficit. During the conference, President Obama mentioned corporate jet owners six times, criticizing their desire to maintain an accelerated depreciation tax break. The President's comments were met with strong criticism from aircraft manufacturers and members of the aviation community. Based on the underlying assumption that new information is rapidly incorporated into stock prices, the press conference likely had a negative impact on the stock returns of aircraft and aircraft parts manufacturers. This paper uses a financial events study to determine whether or not the press conference significantly hurt the stock prices of aircraft manufacturers.

This paper focuses on the consumer expenditure habits in the years following the 2008 recession as compared to Milton Freidman’s Permanent Income Hypothesis. Panel data collected at the household level from the Consumer Expenditure Survey was used to analyze the change in consumption based on the change in income for the years 2009, 2010 and 2011. To achieve a greater understanding of expenditure patterns, this essay also analyzes the income elasticity of demand for elastic goods including expenditure on apparel, food eaten at restaurants, entertainment and transportation. With the use of panel and time series regressions we find that the Permanent Income Hypothesis holds true and consumers only marginally responded to a change in income in their consumption patterns. We hypothesize that the large spike in savings that was seen in May of 2008 resulted because of low consumer confidence, which in turn lead to a change in transitory consumption. Furthermore, we find that older adults spent more money on elastic goods than younger adults. This may be because older adults tend to have other assets that can financially support them in the case of a drastic change in income.

1. Introduction This dissertation consists of six chapters that span a very diverse set of topics. Yet, it has two unifying themes, economics and biology, that tie it together. The first four chapters present the principal findings from a project that was initiated jointly with David Cesarini and Magnus Johannesson, and that applies the twin method from behavioral genetics to economics. The last two chapters instead use a simple regression framework and evidence from biological anthropology to investigate recent claims regarding the effects of child bearing and past slave trades. 2. Genes and economics There is a small, but rapidly growing, literature studying the genetic and environmental origins of economic behavior and outcomes (Bowles et al., 2005; Beauchamp et al., 2011). Until recently, this literature focused exclusively on outcomes, and in particular income. In chapters 1-4 we instead focus on economic behavior and decision-making. Previous behavioral genetic work outside the domains of economics has changed the way that we think about a number of behavioral traits. In this literature it is typically found that i) variation is heritable ii) genetic factors are more important than family environment iii) a large fraction of variation cannot be explained by neither genes nor family environment (Turkheimer, 2000; Plomin et al., 2009). However, compared to many other disciplines, and psychology in particular, economics is lagging behind. In fact, as recently as 2009 the leading text book in behavioral genetics described economics as "still essentially untouched by genetic research" (Plomin et al., 2009, p. 353). Hopefully, the chapters in this dissertation can help to improve on this somewhat unsatisfactory state of the art. Chapters 1 and 2 study economic decision-making in the laboratory using the twin method. More specifically, we study the ultimatum and dictator games alongside risky gambles, using same-sex twin pairs as our subject pool. Given a few additional assumptions, the fact that identical twins have, in expectation, a twice as high coefficient of genetic relatedness as fraternal twins implies that we can study the genetic and environmental contributions to variation in behavior by studying twin correlations in observed choices. Chapters 3 and 4 apply the same method to actual portfolio choices associated with a far-reaching pension reform, as well as to a set of standard behavioral anomalies. Taken together, these four chapters provide strong evidence in favor of the hypothesis that genes influence economic decision-making. Thus, economic behavior does not appear to be much different from other types of behavior. 3. Economics and history The last two chapters of the dissertation turn to the past, rather than genes, in an effort to evaluate recent findings regarding two important welfare outcomes. In chapter 5 we investigate Nunn’s (2008) claim that past slave trades had a negative impact on current economic performance in Africa. By extending the sample period back in time we demonstrate that this relationship was not significant in 1960. In addition, by applying Nunn’s method to an episode of large scale slave raiding in Italy, we demonstrate that there exists a similar negative relationship across Italian regions, although it becomes insignificant when geographical controls are included. Intriguingly, going back to 1960, the coefficient on slave raids for Italy also has a similar time trend to that for Africa. Taking these facts, and our reading of the historical and anthropological literature, which is much different from that of Nunn, into account we do not find much support for the hypothesis that the African slave trades had a negative impact on current economic performance. Finally, chapter 6 investigates the large and negative relationship between giving birth to a son, rather than a daughter, and maternal longevity that was documented in a Sami hunter-gatherer population from Finland (Helle et al., 2002). Using a substantially larger sample of pre-industrial Swedish Sami we find no evidence in favor of such a relationship. 4. Brasklapp Five of the chapters in this dissertation (Ch. 1-4 &amp; 6) are slightly altered versions of previously published papers (Wallace et al., 2007; Cesarini et al., 2009 a, b; 2010; 2011). Unfortunately, the fact that earlier versions of the chapters were prepared as separate articles for five different journals means that they can at times appear both repetitive, and in terms of notation and formatting, somewhat inconsistent. I apologize to the reader for these inconveniences. / <p>Diss. Stockholm :  Stockholm School of Economics, 2011. Introduction together with 6 papers</p>
